If you’ve been playing airsoft for any amount of time, you’ve probably experienced fogging. Fogging occurs when the hot, humid air from your breath condenses on the cool surface of your eye-protection or rifle sight. This water build up can make it very difficult to see anything during a game.

If you look at metal under a powerful microscope, you might expect to see a smooth, shiny surface like you see with your eyes and feel with your fingers. However, what you will actually see is a cracked, mountainous exterior not unlike a satellite photo of the Alps.
